Robolab Programming Software for Schools from the LEGO
educational division. An icon based language that will help
introduce programming concepts and will also introduce
the parent language LabView (an engineering industry standard).
1 site license per school, or perhaps a single copy
to be used on the teacher's demonstration platform @ $70.

Mac 12" iBook @ $1000. 1 per team or total $2000. A school will
certainly have more than enough Windows machine to get started.
The better NQC and USB interfaces for the Mac, however, will
surely decrease teacher and student frustration levels.

In summary, for 2 teams of 4 students, $810 will get you started
using some existing resources at the school. $3000 will get a
completely self contained program started.
